Amorphous molybdenum oxide films with almost 20[Formula: see text][Formula: see text]m thickness are electrodeposited on the Cu foils from a citrate-ammonia molybdate bath containing Ni[Formula: see text] ions. The content of Ni in the oxide films is very low, 0.87 at.%. XRD and FTIR data suggest that they are composed of hydrous MoO2. The multilayer and cracked structures are characterized by scanning electron microscopy (SEM), and are beneficial to transmission of Li[Formula: see text] ions between the electrolyte and anode materials. Galvanostatic battery testing shows that amorphous molybdenum (IV) oxides as anodes for lithium-ion batteries exhibit a high specific capacity of 876[Formula: see text]mA[Formula: see text]h[Formula: see text]g[Formula: see text] at a current density of 50[Formula: see text]mA[Formula: see text]g[Formula: see text], good capacity retention as high as 97.4% after 20 cycles.

Silicon, an anode material for lithium ion batteries, has the highest theoretical specific capacity ([Formula: see text] mAh/g). The actual lithium storage capacity of [Formula: see text] mAh/g is about 10 times that of the graphite anode materials class. This study involves magnesium heat reduction of the SiO2 preparation of silicon carbon composites. The Si/SiC composite shows a high initial specific capacity of 1406.7 mAh/g with a current density of 0.1 A/g. The morphology and pore size inherited from the SiO2 aerogel counteracts the volume expansion during the lithiation/delithiation process. This paper provides an articulate methodology for designing silicon anode material for high-performance rechargeable lithium-ion batteries.

Initial Coulombic Efficiency

The carbon materials prepared by PVDF carbonization at different temperatures have similar BET surface area and pores volume. The content of fluorine in the carbons decreased with the carbonization temperature from 1.46% (atm %) at 600°C to 0.18 %( atm %) at 1000°C. The first cycle specific capacity and the initial coulombic efficiency decreases with the decrease of fluorine content in the samples. The first cycle discharge capacity decreased from 982 mAh/ g at 600°C to 752 mAh/ g at 1000°C and the initial coulombic efficiency decreased from 31.8% at 600°C to 24% at 1000°C. It is believed that fluorine contained in the carbon materials has a positive effect to improve the electrochemical properties as anode materials for Li-ion batteries.
